Product catalog summary

Introduction
This technical catalogue from GGE srl provides detailed information on various ventilation products such as centrifugal fans, exhausters, extraction towers, and evaporative coolers. It emphasizes the importance of ventilation in maintaining air quality and outlines product specifications.

Importance of Ventilation
Ventilation is crucial for removing harmful substances and ensuring air quality, especially in industrial settings where it aids in cooling and air exchange.

Types of Fans

Centrifugal Fans: Suitable for centralized systems, handling medium capacities with high pressure, available in various blade designs.
Axial Fans: Ideal for high capacities with low pressure, available in propeller-driven and ducted types.

Product Specifications

MTV Wall Extractors: High-capacity, self-cleaning extractors made from materials like stainless steel, suitable for industrial and greenhouse use.
VDL, VDV, VDV/LEX, VDQ Exhausters: Wall-mountable helical fans with various blade materials for industrial applications.
TE Extraction Towers: Versatile towers for air extraction in industrial and agricultural settings.

Technical Data
The catalogue includes detailed specifications such as model numbers, dimensions, power requirements, and performance metrics like flow rate and noise levels.

Evaporative Coolers
The MT series uses water evaporation to cool air, offering an alternative to traditional air conditioning, with models like MT30 providing a maximum flow rate of 16,000 m³/h.

Operating Principle
The cooling process involves air passing through a water barrier, absorbing heat and cooling the air, explained through thermodynamic principles.

Applications
These systems are applicable in industrial structures, workshops, showrooms, and warehouses, with guidelines for installation and operation to optimize performance.

Definitions
Key terms such as dry bulb temperature, wet bulb temperature, relative humidity, and enthalpy are defined to aid understanding.

Fan Types and Specifications

Series d (dTd, TRd): Low pressure fans for clean or slightly dusty air, max flow rate 180 to 96,000 m³/h.
Series E (dTE, TRE): Low pressure fans with high efficiency, max flow rate 1,320 to 216,000 m³/h.
Series M (dTM, TRM): Medium and low pressure fans for very dusty air, max flow rate 378 to 96,000 m³/h.
Series O (dTO, TRO): Higher pressure capabilities, max flow rate 378 to 170,000 m³/h.
Series h-V (dTh-V, TRV): Reduced noise fans for very dusty air, max flow rate 378 to 132,000 m³/h.
Series S-T (dTS-T, TRS): Open blade impellers for material transport, max flow rate 480 to 132,000 m³/h.
Series Q-R-X (dTQ-R-X, TRQ-R): High and medium pressure fans for material transport, max flow rate 180 to 54,000 m³/h.
Series I-J (dTI-J, TRI-J): Reduced noise fans for dusty air, max flow rate 120 to 185,000 m³/h.

Fan Selection Criteria
Selection is based on specific weight of the fluid, considering operating temperature, barometric pressure, and installation height. Adjustments ensure performance requirements are met.

Example Calculation
An example demonstrates fan selection adjustments for different altitudes and temperatures to maintain desired airflow and pressure.

Additional Information
Includes a table of air speed values for different materials and notes on data variability and tolerances for flow rate, pressure, and noise levels.
